Application filed February 10, 190?. Serial Hui 360,426.

To all whom it may concerns 7 Be it known that I, BENJAMIN E. BARNEY,

a citizen of the United States, residing at Osawatomie, in the county ofMiami and State of Kansas, have invented certain new and usefulImprovements in Draft Appli an'ces, of which the following is aspec1fication.

This invention relates to draft appliances; and more particularly todraftbars and atmj' object is to produce an appliance oi this characterwhich is exceedingly sim is, strong, and durable of construction, can eeasily: and expeditiously secured in or removed from able to cars ofstandard pattern, and cannot drop to the road-bed should tion becomedetached from the car-sills. r With these and other objects in view, ashereinafter a peer, the invention consists in certain nove and peculiarfeatures of con struction and organization, as hereinafter described andclaimed, and in order that it army he fullynnderstood reference is to behad to the accompanying drawings, in Whichlfigure 1 represents avertical secticn of a I draft appliance embodying my invention,

Fig; Bisa section on the line In the stud drawings, where like reference endingparts, 1 indicates a box-car, 2 one o the end sills and 3 {5f the innerpair of the longitudinal sills thereof. Z '4 indicatesthe transomprovided with the 5 at opposite sides of its center an wit its centralportion provided with a pro 'ect boss 5 edits outer face, so as toprovides at face for a purpose which hereinafter appears, and 6indicates the usual king-belt extending vertically through theReferringnow to the draft a first .to'that part technically upentheupper side position, is adapt- 7 the front per pliances and own as thezontal late extending longitudinally and dispos against the under sidesof the end Slll and sills 3, and said plate is provided with anupwardly-projecting flange 8, mortised into the outer face of sill 2 bypreference Near its rear end the late 7 is bent upward, so as to fitagainst t e outer face and rest of the transom, as at 9, preferablymortised into e-sills 3,7 as at IO. The; king-bolt extends through saidportion 9 of the plate, and a series of vertical bolts 11 also extendthrough said; ortion 9 and the transom and are en- .gag tat their'lowerends b the nuts 12. 13 indicates the side or'c eek pieces of theattachment, the. same extending longitudinaliyfof and below the topplate 7. Near their rear ends they are "slitpvertically, as at theportion 9 being hentooutwardly from the bases of the slits, so as toprovide flanged portions 15 slices depththan the body ortions] 3, whichflanged pore ticns extend t ough' the-openings 5 of the transom with therear ends'aofthe body por the face of boss li e? the transom above andbelow said openings 5, and throughthe open- 15 bolts 1 I extend. Bylthussecuring the rear ends of the bars cannot sa materially should thesupportigag means at are front end; hereinafter describ becomebroken orvotherwise inefl'ective, The bars 13 are provided at their upper andlower margins with outwardly-promoting flanges 1?, the per onesbeing'riveted to the top plate 7. X suitable distance from the front endof the top platebars 13 are bent back'upon themselves, as at 18, and arethen bent, as at 19, to form, the longitudinallyelined andoppositely-(ii osed pockets and 21. The hers are then hent to projectoutwardl E to provide the front end walls 22, posed 3' reference flushwith the outer face of sill 2 and some distdnce outward of the bases ofpockets 21, so as to. provide the interposed ohambers 23, into whlchawrench or equivalent tool may be inserted for a p ose which hereinafterappears. To make t e connection and secure j between the portions-19ofbfis 13 and the to plate,v the former have inwsrdly projecting, anges24 at their nner ends end outwardly pro eetingflanges '25 at theirouter" sides thereof, 7 indicates a hori plate 7, agndto unite" thefront end of the at- 14, and the portions rearward ci the slits aretions' 13 bearingsquarel'y andflatly against ings 16 of the flanges ofsaid reduced portions; 8

' S 13 to thetransorn it will he apparent that the front end of the barssecured by, rivets, 26 to,

tachment reliabl to the car bolts 27 extend .down through si] s 3 andthrough plate 7 and flanges and are engaged at their lower ends by nuts28.

v 29 indicates a bar secured to and between and forming a brace-rib forthe body portions of bars 13 to prevent them bending outward or inward.

30 indicates channel-plates secured to the inner sides of the lower.portion of each pocket to form a bottom for the latter to supporttherein thespiral sprin s or cushions 31.

32 indicatesa plate bridging the space between and underlying thepockets 21 said plate being bent bac at its margins to provideinwardly-opening grooved portions 33, slidingly engaging the owerflanges 25 of portions 19, and the outer end of said plate is bentdownto provide depending flange 34, and said slide-plate is bolted, asat 35, to the engaging flanges ,of portions 19. A slideplate 36, similarin construction and arrangement with reference to portions 19, bridgesthe space between and underlies pockets20 and is bolted, as at 35, tothe He es 25. It is obvious of course that a single etachable plate maybe used in lieu of the twoplates 32 and 36; but the "twolateconstruction is preferred. The slide-p ates prevent the side 3 portions19 from spreading apart and are detachably secured inposition, asexplained, for

convenience in giving access to the interior of the attachment for theinsertion or removal of the springs and also to ermit of the insertionor removal of a locking-nut hereinafter described. A i

37 indicates a yoke shaped biilfer having its face'tapered in o positedirections, as at 38. Bolts 39 exten through the buffer and portions 22of the attachment and are engaged by nuts 40, occupyin chambers 23,these chambers being provi ed for the reception of these nuts and alsoto enable the operator to engage andhold the same by means of a wrenchor other tool.

40" indicates the cou ler-head of the draftbar 41 the latter exten ingthrough the yokeshaped buffer 37 and between the pockets 21 qahato ilate7, and slide-plate 32; The rear 5 end 0 t e stem is formed withoutwardlyprojecting shoulders 42, and said stem is provided with a lori''tudinal passage 43, communicating at its opt end with apassage 44 inthe coupler-head. Q y

3 45, indicates a tie-bolt extending through assages 43 and 44 andhavingits angular liead 46 countersunk in the coupler-head, so

that it cannot turn therein, and its threaded end engaged by an oblonrectangular locking-nut 47, which fits sli ingly between portions 19,top plate 7, an the slidelates 32 and 36, so that as long asthe head 0is countersunk in the couplinghead there is no possibility ofdisconnection between the 55 bolt and nut 47 unless a breakage of onethe bolt or the other occurs. ployed so that in case the draw-bar breaksatv any point between its head and shoulders the broken parts will beheld together. Should the draw-bar and bolt both break, the forwardparts would be withdrawn and fall to the road-bed, but would do nodamage because the car would pass over them without contact. It is obvius that the entire drawbar cannot bewith awn because shoulders 42 andnut 47 would be resisted by that portion of the attachment in theirpath. It will also be a parentthat if either or both shoul ders of t edraw-bar should become broken the tie-bolt and locking-nut connection,in ooo eration with the attachment, would hold t e draw-bar in placeuntil an opportunit for repair occurred, the tie-bolt being of enficient strength for the purpose.

In practice the coupling of a car e uipped with this draft appliance.would resu lt in inward movement of the draw-b ar, the springs 31 inpockets 2O cushionin such movement, the proportions being sue thatbefore the cusluons could be compressed sufficiently to break them thelocking-nut would come into contact with the inner walls of the pockets,which thus form abutments to positively limit the inward movement of thedraw-bar. After the coupling action the outward pull on the draw-barwould be resisted by the eush ions or springs in pockets 21, the outwardmovement of the draw-bar being limited before a destructive pressure wasimposed on the springs by the contact of the shoulders 42 was the innerwalls of the pockets 21, as will I be readily understood by reference toFig. 6 particularly.

From the above description it will be appar-. cut that I have produced adraft appliance for boxcars which possesses the features of advantageenumerated as desirable and which obviously ma be modified in minorparticulars without epartin from the principle of construction involveHaving thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is r 1. The combination with a car, of adrawbar attachment having pockets opening toward each other, the pocketshaving their inner walls forming abutments, springs in said pockets andpro'ecting beyond and of greater ength than sai inner walls, and adraw-bar havin laterally-projecting portions interposed between saidinner walls and between said springs.
